    (54) Anti-spillage and anti-drip device


    (57) Two or more relatively fine mesh screens (13) are placed in a liquid flow path to allow gas or air or liquid under pressure to pass through but to prevent unpressurized liquid from flowing through. In one application the device may be attached to a vent opening of a liquid container to permit air into the container while preventing liquid from spilling out of the container through the vent opening. In another application the screens may be used in the flow path for liquid under pressure to prevent dripping of the liquid after the pressure has been removed.
